Perambulator skeleton as described above, it is characterised in that：Described push bracket 3 includes push rod section 31, described push rod section 31 Upper end provided with the hinged block 32 for protruding its outer peripheral face, described handspike 4 includes top push rod 41 and bottom push rod 42, described Push bracket 3 be hinged on top push rod 41 and the joint of bottom push rod 42, described hinged block 32 is provided with to be blocked for bottom push rod 42 The card entry slot entered.

Compared with prior art, the utility model has the following advantages：

1st, the utility model promotes handspike and pushed when folding, forward, and therefore, push bracket is rotated relative to back leg, and first Trace is also rotated relative to back leg, and when the first trace is rotated relative to back leg, the lower end of the first trace is upturned, so that The second trace is pulled, then pulls foreleg to be drawn close to back leg by the second trace, in the process, the first trace is also pulled Mounting bar is rotated relative to back leg, and final front-wheel is drawn close to trailing wheel, push bracket upper end is drawn close with handspike upper end on back leg to trailing wheel End is drawn close, so perambulator volume compact after folding, occupies little space.

2nd, after the utility model is folded, the lateral shaft of connecting seat hack lever and foreleg is then received into opening on the second trace In mouth groove so that perambulator skeleton volume after folding is compact.

3rd, push bracket of the present utility model includes push rod section, and the upper end of push rod section is provided with the hinged block for protruding its outer peripheral face, hand Push rod includes top push rod and bottom push rod, and push bracket is hinged on top push rod and bottom push rod joint, and hinged block is provided with confession The card entry slot that bottom push rod is caught in.When perambulator deploys, bottom push rod is accommodated in the card entry slot on hinged block, and structure is tighter Gather, profile is more attractive.

4th, the utility model is simple in construction, easy to operate, and small volume, cost is low, is adapted to popularization and application.
